In West Africa two rice species (Oryza glaberrima Steud. and Oryza sativa L.) co-exist. Although originally it was thought that interspecific hybridization is impossible without biotechnological methods, progenies of hybridization appear to occur in farmer fields.

The Jeypore tract of Orissa, India is famous for the genetic diversity of Asian cultivated rice and has been considered the center of origin of aus ecotype. The landraces or traditional varieties growing here are thought to harbor dominant genes for biotic and abiotic stresses, aroma and palatability and hold promise for their utilization in future plant breeding and biotechnology programs.

THIS is the variety of rice without which biryani, the royal gastronomical delight, would not feature so prominantly in the history pages on Mughal influence in India. Aromatic, long-grained, nonsticky are the words that describe it. It is the Basmati. India grows 1.6 million tonnes annually. Two-thirds is exported every year. India claims its traditional knowledge of the climate, the

Plant growth promoters are naturally produced molecules that increase crop yield. Developing them for commercial use is difficult. The Central Institute of Medicinal and Aromatic Plants (CIMAP) received a US patent in May, this year, for developing a promoter, isolated from a medicinal plant. Anil Kumar Singh, Deputy Director of the chemistry division, spoke to Savvy Soumya Misra An ongoing

ornithology Birds love noise The house finch and the black-chinned hummingbird are unaffected by noise pollution. In fact, they prefer to nest in noisier areas because it increases their chances of survival. A team isolated the effects of noise pollution on bird communities. For this they chose regions with natural gas extraction plants which contain noise-generating compressors. The

Pink bollworm (PBW, Pectinophora gossypiella Saund.) is a pest of economic importance in cotton producing countries. Earlier results of host-plant resistance to the PBW indicated races of Gossypium hirsutum L. and some wild species including Gossypium thurberi Tod. which are resistant to PBW. Hence prebreeding

When subject to flooding, deepwater rice survives by shooting up in height. Knowledge of the genetic context of this and other responses to inundation will be a boon in enhancing rice productivity.
